Oat grain flour can be hard to track down - Bob's Redmill makes it and I usually find it at Whole Foods.

Swapping whole-grain oat flour for all-purpose flour removes standard gluten development, yielding a structurally delicate pancake that requires careful handling. Without wheat gluten to trap expanding carbon dioxide, this batter relies entirely on the reaction between baking soda and reduced-fat buttermilk to achieve a light interior. Using frozen blueberries directly from the bag without thawing prevents excess moisture from bleeding into the batter, which would otherwise create heavy, wet spots.
An electric frying pan or griddle offers the precise temperature control needed here, unlike standard stovetop burners that create uneven hot spots. Heat the surface until it reaches a stable 375 degrees Fahrenheit before portioning the batter in 1/8-cup measures. Because oat flour contains less starch than refined wheat, these cakes will not produce the characteristic surface bubbles associated with traditional pancakes. Watch the perimeter instead; flip the cakes precisely when the edges turn opaque and firm up, which generally takes about two minutes. Cook the second side for an additional two minutes until golden brown.
